ESG scores can't be retreived

Suddenly the ESG scores are missing. Probably Yahoo made a slight modification in its data structures.

```
>>> from yahooquery import Ticker
>>> aapl = Ticker('aapl')
>>> aapl.esg_scores
{'aapl': 'No fundamentals data found for symbol: AAPL'}
```

I have found this problem for a large number of equities, so it isn't an apple problem.
